- Rapidly rotating sub-stellar objects
- Abstract
-
Almost all stars and sub-stellar objects have rotation, and some sub-stellar objects display rapid rotation.
Beta Pictoris b is one of the fast spinning exoplanets, and its rotation velocity is higher than those of planets in the Solar system.
Some brown dwarfs also have rapid rotations, and their rotation periods are only a few hours.
The shapes of rapidly rotating sub-stellar objects might be deformed due to the strong centrifugal forces, and non-spherical models are required to describe them.
In order to consider the structures and evolution of rapidly rotating sub-stellar objects, we calculated both thermal evolution and rotating structures of them using MESA code and our numerical code for obtaining structures of rotating stars.
In this talk, I will review some observations of rotating stars and sub-stellar objects and discuss the shape and evolution of rapidly rotating sub-stellar objects. - 連絡先

- Title
- World of turbulence in magnetically confined plasmas
- Abstract
-
Turbulence and spontaneous shear-flow generation are ubiquitously observed in astrophysical and laboratory plasmas, such as the sun and magnetically confined fusion plasmas. In particular, the turbulent transport driven by kinetic microinstabilities with the ion/electron gyroradius scale is a long-standing critical issue in the laboratory plasma research. In this talk, several recent topics on the turbulence research in confined plasmas, e.g., how the turbulence develops, how the turbulence is measured/simulated, how the shear-flow suppress the turbulence, how the turbulence can be controlled, are presented. Also, our cross-disciplinary activity between
SOlar and LABOlatory plasma researches, **SOLABO-X, is introduced.**SOLABO-X: NINS program for cross-disciplinary study on Turbulence, Transport, and Heating Dynamics in Laboratory and Solar/Astrophysical Plasmas
